personalisation 3 77. If deactivated,
m illuminates in the instrument
cluster and a warning message is
displayed in the Driver Information
Centre. When ignition is switched on next time, system is activated.The feature uses various inputs (e.g.
camera sensor, radar sensor, brake
pressure, vehicle speed) to calculate
the probability of a frontal collision.9 Warning
This system is not intended to
replace the driver responsibility for driving the vehicle and looking
ahead. Its function is limited to
supplemental use only to reduce
the vehicle speed before a
collision.
The system may not react to
animals. After a sudden lane
change, the system needs a
certain time to detect the next
preceding vehicle.
The driver must always be ready
to take action and apply the brakes and steer to avoid collisions.
9 Warning
The usage of a license plate
support may have an impact on
the proper operation of the radar
unit and may limit sensor
perfomance. Vehicles or
pedestrians driving or walking
ahead may not be detected by the
system.
Do not use a a license plate
support to ensure proper system
functionality.
Functionality
Depending on the vehicle
configuration and the detected
objects, there are several operational speed ranges.
On vehicles equipped only with front
camera, the active emergency
braking operates from 5 km/h to 80 km/h when a vehicle has been
detected.
On vehicles equipped with radar
sensor and front camera, the active
emergency braking operates from
5 km/h to 140 km/h when a vehicle
has been detected.
Active emergency braking only works when the seat belts of the front
passengers are fastened.
